Abstract
This paper proposes an improved position sensor fault detection based on back-electromotive force (back-EMF) estimation in an interior permanent magnet synchronous motor (IPMSM). The threshold value in order to detect the position sensor fault of rotor is one of the most important things in IPMSM drive system. This threshold value should be designed by a higher value than the maximum overshoot of estimated angle error caused by acceleration or deceleration of motor as well as steady state error. In this paper, the fast fault detection method using adaptive threshold design is determined and proposed method is verified in transient state such as acceleration and deceleration by simulation and experimental results.
